How to install primer bulb
For model number PPT 260
Hello Joe, Thank you for your inquiry.You would remove the air cleaner cover, then remove the screws that hold the carburetor on the motor. Next remove the four screws from the primer pump housing. Take the housing place off and remove the bulb and place the new bulb into the housing and replace the screws that attach the housing to the carburetor. Mount the carburetor back onto the motor and replace the air filter cover. Hope this helps!
